To all whom it may concern: 7

Be it known that I, EDWARD G. GERMER, a.

citizen of the United States, residing at Erie,

in the county of Erie and State of Pennsylvania, have invented new and 'useful, Im-

provements in Fire-Pots or Linings, ofwhich the following is'a specification.

This invention relates to fire pots or linings, and consists in certain improvements in the construction thereof as will be'hereinafter fully described and pointed out in the claims.

The objects of the invention are to both cheapenthe construction of the pot, and to, increase the efliciency of the same.

The invention is illustrated inthe accompanying drawings as follows: Figure 1 shows a plan view of the pot. Fig. 2 a section on the line 22 in Fig. 3. -Fig. 3 a section on the line 33 in Fig. 2.

1 (1102,1308 the fire pot taken asa Whole. 2 a portion of the stove on which the fire potordinarily rests. The fire pot is provided 'with a series of cells 3, these being cast in the walls of the pot. These cells register with perforations 4 in the support 2 .by means of which air is delivered to the cells. The slits 5 connect the cells with the interior of the pot, and preferably extend from top to hotthe pot. I more even introduction of air to the fire chamber -Within the pot.

characteristics have been heretofore utilized,

tom of the pot, and are also preferably continuous, so as to allow for free expansion and contraction of the metal forming the walls of Thecontinuous slit also assures a These general as for instance in the construction shown in my former patent August 3, 1897, No. 587,366.

In the present constructidn the inner walls of the co ls project into the fire pot beyond theintervening walls7. In this'manne-r a greater quantity ofburning fuel is brought nearer to the opening. For example in my former patent all the fuel within. a given radius of the opening is'included in less'than a semi-circlev viewed in cross section.

. Whereas in the pres'entconstruction the fuel I mass within a in the'entire pot is considerable.

cells projecting outwardly from the general line of the intervening walls.

Jmann'er ofconstruction the walls of the cells -may be made somewhat thinner, and 1nas-, I

much as there are many of these, the saving Furthermore the Walls of the cells with relation to the intervening walls may be iven a more uniform thickness, 'thus equa izing the strains incident to contraction and expansion.

jecting inwardly and the outer walls of the With this,

It will'also be apparent, that a greaterpor- 7 tion of the wallssurrounding the cells are directly'exposed to the burning fuel, so that the walls are heated to a higher degree, thus assuring more uniform'temperature between v the outer walls of the cells, and the interveningwalls of the pot. That this 1s an mportant consideration is evident from the fact, that the outer walls of the cells form small vertical sections, which are exposed on the outside to from the direct action ofthe fuel, so as to be much cooler than other arts of the pot, which are directly ex osed to the action of the fuel. -Anything, t erefore, that tends to decrease. this difl'erenceof temperature is important, and this construction in connection with the continuous slits relieves the .pot very largely of all injurious strains.

' Whatl claim as new is:

1. A fire pot or linin arranged inits wall am? continuous openings from the cells to the part of the fire pot or lining normally occupled by fuel, said openings extending approximately from the top to the bottom of the fire pot or lining, the inner walls of the eells(pro ecting'into the fire pot or lining beyon tions of the Wall and the intervening POItlOIlS of the wall being free from obstructions preventing the fuel rom filling the space between the projecting walls. I v

Afire pot or linin having vertical cells arranged in its wall, an continuous openings from the cells to the part of the fire pot or lining normally,occup1ed by fuel, said openings extending approximately from top to bottom of the ot or lining, and the inner and outer walls of the cellsprojecting from the intervening portions of 'thewall.
